Documentary about the murder of Southport mum Lynsey Quy is to be broadcast on Monday

A DOCUMENTARY about the murder of Lynsey Quy is to be broadcast on Monday – nearly two years after being postponed.

‘Real Crime: The Cat and Mouse Killer’ profiles how Mitchell Quy went to extreme lengths to attempt to prove his innocence after brutally killing his wife in December 1998.

In a staggering show of bravado, the killer, described by police as “an arrogant and egotistical person who started to believe his own story” courted the media – appearing on This Morning, on local news programmes and in the Visiter.

Using footage from a fly-on-the-wall ITV documentary which Quy appeared in during the investigation, he is shown at home, decorating and looking after the children while protesting his innocence.

He taunted the police with phone calls and Christmas cards because he believed he would never be caught, but the documentary tells the story of the police investigation that nailed him.

It features the voice recordings from his police interviews, police video footage and emotional interviews with Lynsey’s family.

Lynsey’s dad Peter Wilson said: “We signed the disclaimer for the show about four years ago and I got the call a couple of weeks ago to say it was finally being broadcast.

“Some of the family don’t want it to be shown but I think it is important that no-one forgets just what this man did.

“His brother, Elliot [who helped Mitchell dismember and dispose of the body] is out of prison now and he could be going out with somebody’s daughter. They might not know who he is.”

The programme features the police tape of Quy’s confession. He says he spoke to his brother about how to get rid of her and they decided to cut the body into pieces.

Quy was jailed for life in 2001 but is expected to be released in 2017.

Peter added: “There is not a day that goes by when I don’t think about Lynsey.”
